How Hail Can Cause Roof Leaks and Water Damage
Hail can damage a roof, leading to leaks and serious water damage if left unrepaired. What might be a small issue, in the beginning, can spiral into a major water damage disaster requiring both roof repair and water damage restoration for a Waxahachie home or business.
According to roofing experts, “The average hailstorm lasts only five minutes, but the hail damage they leave behind totals about $1 billion a year, according to the National Weather Service. When hail hits, it can damage the roof of your home as well as other personal property… Hail damage on a roof looks like indentations and/or fractures on the shingle’s surface. Hailstones vary in size, shape, and hardness and can create a random pattern of dents or depressions.”
Hail size impacts roof damage.
Generally, the larger the hailstone, the greater the damage it can inflict. However, other factors come into play when dealing with hail damage, such as the shape of the individual hailstone and the speed at which the hail impacts the roof.
Hailstones form when warm updrafts carry water droplets to high altitudes where the temperatures are frigid. The droplets freeze and combine until they are heavy enough to escape the updrafts. At about one-quarter inch in diameter, hailstones begin their downward plummet. Amazingly, hailstones can range in size from a small pea to larger than a softball and can weigh as much as one pound. According to the National Oceanic and Atmospheric Administration (NOAA), the largest hailstone on record in the US measured over eight inches in diameter and weighed over a pound. While small, pea-sized hail rarely damages a roof, dime-sized and quarter-sized hail often severely damages a roof.
Shape can impact hail damage.
The hail formation process creates hailstones of various shapes and sizes. On rare occasions, some hailstones can develop sharp points or edges. When that is the case, small hail can cause great damage. Homeowners should be aware that small hailstones with jagged edges can puncture shingles that have been recently installed. A roof inspection after a hailstorm is a wise course of action.
Hail speed impacts roof damage.
Hail begins its descent from as high as 30,000 feet and will gather speed until terminal velocity or top speed is reached. Wind direction and speed can influence a hailstone’s speed. Wind-driven pea-sized hail impacting a roof at high velocity can compromise the shingles’ ability to keep out moisture. Hailstones the size of baseballs or larger can reach speeds greater than 100 miles per hour. Most roofs are no match for such a fierce barrage.
Roofing materials impact hail damage.
The highest quality thirty-year laminated roofing shingles act as armor in a hailstorm. Best quality shingles can still sustain damage under the onslaught of large, jagged hailstones impacting the roof at high speeds. Other roofing materials such as metal, tile, slate, and synthetics are durable, but the impact from a four-inch hailstone traveling at speeds over 100 miles an hour will at least inflict a measure of cosmetic damage to even the toughest of roofing materials.
The age of the roof impacts hail damage.
A 3-tab asphalt shingle will last from 12-15 years. A well-maintained metal roof will endure for sixty or more years. Architectural laminated shingles are rated at thirty years. All roofing materials will lose durability over time. Homeowners with older roofs should be vigilant in their watch for roof leaks after severe weather, especially weather involving hail and high winds.
The Danger of Small Hail Damage
Small hail damage may require a trained eye to spot. Small damage can lead to small leaks that, if left unrepaired, can cause big problems such as rotted support beams, mold-infested insulation, ceiling stains, and damage to items stored in the attic. The advanced secondary water damage will only worsen if not treated promptly by a skilled water damage restoration company, such as SERVPRO of Waxahachie/Midlothian.
